KYIV (QHA) - Ukraine's parliament has concluded an extraordinary session without agreeing on a bill to allow former Prime Minister Yulia Tymoshenko to travel to Germany for medical treatment, Radio Free Europe informs. Speaker Volodymyr Rybak declared the session closed after a parliamentary working group made up of President Viktor Yanukovych's ruling Party of Regions and opposition representatives failed to agree on a joint text for the bill. Some deputies shouted "Shame!" after Rybak's announcement. The session was attended by top EU envoys Aleksander Kwasniewski and Pat Cox. The EU has threatened to suspend the signing of association and free-trade agreements with Kyiv at a summit in Vilnius later this month unless a decision on Tymoshenko's release is made by November 13. Meanwhile, Kwasniewski, a former Polish president, and Cox, a former European Parliament president, are due to deliver a report on Ukraine in Brussels later on November 13. Ukraine's union of industrialists and businessmen late on November 12 called for a delay in signing the EU deal, saying it was harming trade relations with Russia and Kazakhstan. The EU is due to decide November 18 whether the deal should be signed in Vilnius on November 28-29. Critics accuse the Ukrainian government of using "selective justice," or politically motivated prosecution, against Tymoshenko.
